Air-Conditioning and Ventilation

Help the cooling system do less work

Cooling needs change with room size, ceiling height, sunlight, insulation, occupancy, equipment, and how often doors open. Ask a qualified supplier or professional to assess the space instead of choosing capacity from floor area alone.

Before and during use

• Close unnecessary openings and use curtains, blinds, or exterior shading to limit direct heat.
• Choose a comfortable thermostat and fan setting rather than repeatedly forcing the lowest temperature.
• Use a fan to improve air movement when appropriate, but switch it off when the room is empty.
• Keep supply and return airflow clear of furniture, curtains, and stored items.

Care and troubleshooting

• Clean accessible filters at the interval in the manufacturer's instructions.
• Arrange professional service when cooling weakens, water leaks, unusual sounds appear, or electrical protection trips.
• Keep outdoor units clear of obstructions without opening or repairing electrical or refrigerant components yourself.
